Foot throttle control

FOOT THRGTTLE CONTROL,

l ,tltifi ieai Application filed September To all whom it iii/1y concern.

Be it known that I, (Jrmnnr s A. Dnsonnnn, a citizen of the United States, residing at Portland, in the county of Multnoniah and State of ()regon, have invented a new and useful Foot Throttle Control, of which the following is the specificiation.

My invention relates to the foot throttle of motor driven vehicles, in that the device is installed under the toot board of the vehicle and so arranged as to prevent the regular opening and closing or" the throttle, caused by the pressure of the feet when driving over rough and uneven ground.

The objects oi? my invention are to install an oil governed spring so that the motion of the foot can be controlled, and the throttle can be held in the same position when the vehicle is being driven over rough ground. A second object is to provide means whereby the throttle can be operated separate from the control whenever it is desired.

1 attain these objects by the mechanism illustrated in the accompanying drawing, in which:

Figure l is an elevational view partly in section, showing the throttle foot pedal,

the throttle control. and lever, the manner in which the several parts are installed above and below the foot board oi the vehicle so as the same can be operated by the foot of the driver. Figure 2 is a sectional view of the control showing the piston, the spring and the cylinder which forms the oil chamber.

Similar numerals refer to similar parts throughout the several views.

The control is in the form of a cylinder 1 having a cap on the lower end with lugs 2--2 which form means for fastening the control to some convenient part 3 of the vehicle trame. On the opposite end of the cylinder is the cap 4t carrying the packing nut 5, through which passes the piston rod 6 having attached to the end. within the cylinder, the piston head 7. A small opening 8 is provided as shown in Figure 2, through which the oil within the cylinder can pass from above the piston head to the chamber below and return as the piston moves in the cylinder. Under the piston head is the coil spring 9 which causes the upward motion of the piston.

Fastened to the foot board 10 is the ful Specification of Letters Patent.

Patented 23, 111.922..

Serial No. 504,038.

crum 11 about which the pedalv 12 is movable. The control is placed in such position under the foot board, that the piston thereof will pass through the opening 13 in said foot board and come in contact with the pedal at the point 14-.

Through a second opening 15 in the :toot board, the :foot throttle 16 passes from the mechanism below to a point above, where it can be operated by the loot oi. the driver. The control. and lever are installed in such manner that the pedal will fall in the position shown in Figure '1 of the drawing. It will be seen that the foot throttle and the control will be operated at the same time when the pressure of the drivers foot is applied to the pedal.

lVhen the vehicle is being driven over uneven ground, the control will operate slow enough to prevent the pressure of the foot from opening and closing the throttle valve which causes uneven driving of the car. It will be noted in Figure 1 of the drawing that the pedal can he placed in the position shown by the dotted outline and the foot throttle can be operated independent from the control.

Having :fully described my invention, 1 claim, and desire to protect by Letters Patent:

.l. in combination with a loot throttle, an oil governed spring control comprising a cylinder closed at each end, a packing nut through which a piston rod passes and has attached to the end within the cylinder, a piston head, said piston head having an opening therein through which the oil within the cylinder can pass, a coil spring installed within the cylinder and on the opposite side of the piston head from the piston rod, a pedal so installed as to fall in cont-act with the end of the piston rod and the foot throttle, so that the control and foot throttle will. both be operated by the pressure of one foot of the vehicle driver and prevent the uneven opening and closing oi. the throttle valve which is caused by driving the car over uneven ground.

2, In combination with a foot throttle, an oil governed spring control comprising a cylinder closed at each end and filled with oil, a packing nut through which passes a piston rod having attached to the end within the cylinder a piston head which is operated in one direction by a coil spring also installed within said cylinder, a pedal movably mounted about its fulcrum and so placed above the foot-board as to fall in contact With 5 the piston rod and foot throttle, so the mechanism of the control and the foot throttle can be operated by the pressure of one foot of the driver, or the pedal can be moved to the opposite side of the fulcrum from the foot throttle and said throttle can be operated independent of the control substantially as shown and described.
